MASSACHUSETTS, A CORPORATION OF MAS- srnmnie MACHINE.

Application filed December This invention relates to the housing of thetwisting heads of machine for spinning wool, cotton, or cotton waste andthe principal object of the invention is to provide a construction of atwisting head housing made of sheet metal which may be readily openedwhenever access to the twisting heads is desired and is readily detachedfrom the machine with a minimum amount of time and labor on the )art ofthe operator.

Practical embodiment of the invention is represented in the accompanyingdrawings, in which- Figure 1 represents a side elevation of afragmentary portion of a spinning machine showing my invention thereon.

Figure 2 is a plan of Figure 1. Figure 3 is a sectional elevation online 3-3 of Figure 1 showing in full lines my improved housing in itsnormal closed position and in dotted lines its open position, it alsoshows in dotted lines its position when about to be detached from themachine.

In spinning machines of this type as at present constructed the twistingheads are guarded by sections of angular iron bolted to the twistinghead brackets thereby necessitating the removalof a section wheneveraccess to the twistin heads is desired. This entails considerable aboron the part of the operative and also lessens the productive capacity ofthe machine due to the necessary stoppage required to effect the change.

My improvement obviates these faults as access may be had to thetwisting heads without stopping the productive capacity of the machine.

In the accompanying drawings, illustrat ing the invention, 10 designatesa stationary 49 rail in the framing of the machine, 11 the twisting headbearing supports in a fixed relation to the frame of the machine, 12 thetwisting heads rotatable in bearings 13 supported by the brackets 11,and14 are i the drawin rolls. To protect the twisting heads and t ieirbearings from damage from any source a housing, preferably made of sheetmetal, is provided made up in sections of convenient length for easyhandling. Each section consists of a back member 15 and a front member16 adapted to abut against each other at the centre line of a pluralitof twisting heads, the abutting edges 0 the two members havingoppositely disposed semi-circular openings each loosely 27, 1926. SerialNo. 157,109.

eml'iracing the upper part of a twisting head. The back member 15 isfixedly connected at each end on the top of the brackets 11 by a screw17.

Fixed to the under side of the back member 15 are hangers 18 on whichthe member 16 is supported and is detachably connected thereto by meansof dowels 19 fixedly connected to the member 16 and slidably mounted ina socket in each hanger 18. The 0 en space between the lower edge of themem er 1.6 and the top of the drawing rolls 14 is covered by the shutter20 thus guarding the twisting heads and their bearings. The shutterswingably mounted on the lower edge of member 16 by hinges 21 ismaintained clear of the twisting beads by abutting against the stop 22on the lower part of the hanger 18.

The shutter in combination with the back member 15 and front member 16forms an effectual guard for the prevention of injury to the twistingheads and yet ready access is given to the beads by the operative merelyraising the shutter to the position shown by dotted lines in Figure 3,and if desired the front member with its attached shutter may be removedfrom the machine by the operative simply lifting them so that the dowelson the front member are clear of their re spective sockets. This latterfeature is especially valuable when applied to spinning machines havingdetachable twisting heads such as shown in a (co-pending patentapplication filed December 11, 1926, Serial No. 154,211 for the reasonthat these twisting heads may be removed from the machine with a minimumamount of labor and time.

What I claim, and desire to secure by Letters Patent, is

1. In a spinning machine having a plurality of twisting heads, al'musing for said head-s comprising a back member fixedly connected tothe top of the twisting head bearing supports, a front member abuttingsaid back member and detachably supported thereby, and a shutterswingably mounted on the front member.

2. In a spinning machine having a plurality of twisting heads, a housingfor said heads comprising a back member fixedly connected to the top ofthe supports for twisting head bearings, hangers fixed to the under sideof said back member, a front member abutting said back member anddeta-ehably supportedon the hangers, and a shutter swingably mounted onthe front member.

3. In a spinnin machine having a plu- 5 rality of twisting heads, ahousing for said heads comprising a back member in a fixed relation withthe top of the twisting head bearing supports, hangers fixedly connectedto the under side of said back :member, a 0 front member abutting saidback member on the centre line'of a plurality of twisting heads,semi-circular openings in the abutting edges of the members adapted toloosely embrace the tops of the twisting heads, a socket in each hanger,dowels fixed to the under sideof front member, a shutter swingablymounted on the front men'lber and a stop :limitingthe movement of theshutter.

In testimony whereof, I have signed this specification.
